Headway is a great idea that turn out to be a good app.
Being able to tap into ideas in 15min is great. I've been using it a lot.
In my opinion the problems are:
- AI voice, very good, but one is able to understand that a machine is speaking.
- Probably AI written, from Sapiens: “Roughly 300,000 years later, matter and energy evolved into atoms and molecules, revealing the secrets of chemistry. Biology first appeared 3.8 billion years ago with the emergence of the first organisms.” So biology appeared 3.5 billion years earlier than atoms and molecules. This is an example of something that doesn't make sense, there are others.
- Regardless of the scope and dimension of the book, the number of key points and length is the same. There are books that should have a more in depth summary, like Thinking fast and slow, or Behave, or others alike.
Having said this, for the price this is great, even if only as a way to check if a particular book is worth reading.
